HOSE-COUPLING.

SPECIFICATION -forming part of Letters Application tiled September 7. 1889.

To all whom it may concern:

Be it known that I, NIcHoLAs J. lSi'nNi-J, of Kansas City, Jackson count-y, Missouri, have invented certain new and useful lmprovements in Hose-Couplers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in Spanner-wrenches for use in coupling and uncoupling hose-pipes such as are employed by fire departments; and it consists in a certain novel construction and arrangement. of parts,as fully set forth hereinafter in connection with the accompanying drawings, and specifically pointed out in the claims hereto appended.

The wrenches now in use by the tire departments for connecting the sections of hosepipes are so constructed as to be applied with difficulty, thereby necessitating a useless expenditure of time; and therefore the object of my invention is to provide means whereby the wrench may be quickly and accurately applied to enable the sections of the hosepipe to be more rapidly connected.

In the drawings, Figure l represents a perspective view of the improved spa-nnerwreneh applied to the coupling of a hosepipe, the Spanner being tipped up slightly to show its groovcd or channeled under side. Fig. :2 is a side view of the spanner-wrench. and Fig. 3 is a view of the same, looking at its under channeled surface, with the handle broken away.

In Fig. l the adjoining sections d. and f of hose-pipe are connected by the couplingband e, which is provided with the usuallugs n c, and the spanner-wrcnch A is provided with a curved head or arm which conforms to the shape of the said coupling-band and is provided with a longitudinal slot gto fit over and engage one of either of the lugs c r'. The curved head of the implement is further provided, in extension of theslot y, with agroove or channel I), the sides C of the slot being flared downwardly, as shown clearly in Fig.

slot g, and a heel Z1 at the junction of the said Y increasing gradually in depth to the said slot` re handle and head, as described.

8. A Spanner-wrench formed oi' a single piece of metal and consistingT of a handh having a curved head on one end thereof and a heel at the junction of the said head and handie, a slot in the forward end of the saidhead, and a groove upon the inner surface o1" the i said head, commencing at the said heel and 1 i l l Patlt No. 455,606, dated July 7, 1891.

Serial No. 323,276. (No model.l

o. The inner end ot the head terminates in a heel I, and a handle ll is provided to enabltl the tool to be readily manipulated.

'lhe groove or channel, whieh.as above described, is formed in extension of the slot, serves to guide the head of the Spannerwrench as it is applied to thelug on thecoupling-band, thereby insuring the quit-l; and eifective application of the wrench and avoiding the risk of a failure to engage the lug in the slot.

lleretofore it has been the practice to provide spanner-wrenches with small openings or perforations to receive the lugs ou the coupling-band; but it will bc seen thatin the haste t-o connect the sections of the hose it is ditiicult to place said opening over the lugr and two or three attempts are necessarybcfore the same can be accomplished.

In using the improved spanner-wrcnch it will bc found a simple matter to place the curved head over the lug so that the latter will enter the slot or the groove, after which it is merely necessary to slide the wrench rearwardly or toward the operator to bring the lug to the outer end o of the slot. 'lhus time is saved and the wrench can be applied in the dark with the same facility as iu daylight.

Having thus described my intention, l claiml. As an article of manufacture, the spanner-wrench, as herein shown and deseribtal, the handle B, having a single curved head A, provided with an elongated slot g, with inclined sides C,saidhead A having on its under side a groove D, commencing at the heel /1 and increasing gradually in depth to the slot g, thus forming a guivlefor the lugs l' to the said slotl g.

i. A Spanner-wrench consisting of a single piece forming a handle l; and a curved head C on one end thereof, the said head having an elongated beveled slot g in one end and having a groove D upon itsiuncrsurface,t11e forward end of the said groove being deeper than its rear end and connected with the said with which it is connected, as described.

In testimony whereof Iaitix my signature in presence of two witnesses.
